▎ 摘 要
NOVELTY - Manufacturing a nanocrystalline cemented carbide material involves stirring and pulverizing a mixture containing metal carbide powder and graphene to form nanopowder having an average particle diameter smaller than that of the mixture; and applying a pulse current to the nanopowder while pressing the nanopowder. USE - Method for manufacturing a nanocrystalline cemented carbide material. ADVANTAGE - The method enables to manufacture a nanocrystalline carbide material having excellent mechanical properties, improved hardness, strength and fracture toughness. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart for a method of manufacturing a cemented carbide material.
